Abstract: An apparatus having a smart material actuator, a support structure and at least one temperature compensating material insert, either externally mounted to the support structure, integrally formed with the support structure, or any combination thereof. The apparatus includes a mechanically leveraged electrically stimulated smart material. The support structure and actuator are susceptible to the effects of differences in thermal coefficients of expansion of the materials used in the construction. The smart material typically displaces less than 0.001 inches and is leveraged up to fifty times to obtain useful movement. The temperature effect on the smart material is therefore leveraged and amplified producing undesirable motion in the apparatus with ambient and/or operating temperature changes. A method for dimensioning and placement of a compensating insert with respect to the support structure provides an accurate and cost effective compensating insert.

Abstract: A cycle engine converting thermal energy to electricity includes a cylinder housing having a piston having two oppositely disposed heads and mounted for reciprocating inside the cylinder. The cylinder is disposed between a hot zone to supply hot gas to one piston head and a cold zone to receive discharged hot gas from another piston head, and to transform the discharged hot gas into a liquid. The hot zone supplies hot gas into the first piston head, while the second head discharges hot gas to the cold zone. This action creates a pressure differential between the two piston heads that causes the piston heads to move in one direction. Thereafter, the hot zone supplies hot gas to the second piston head, while the first piston head discharges hot gas to the cold zone, thereby creating pressure differential between the heads causing the piston to move in another direction. The piston is provided with a permanent magnet coupled to electric coil. When the piston reciprocates, it creates a magnetic influx in the electric coil, which is transformed into electricity in the coil.

Abstract: A multi-dimensional, micro-electromechanical assembly and the method of fabricating same. The invention enables an assembly of three-dimensional (3D) microelectromechanical systems (MEMS) using surface tension or shrinkage self assembly. That is, the invention provides a surface tension self assembly technique for rotating a MEMS element with a controlled amount of deformation to a selected angle out of the plane of a substrate. In accordance with the inventive method, multi-dimensional, micro-electromechanical assemblies are fabricated by providing a phase change material on at least one substantially planar structure mounted in a first orientation. A phase change is induced in the phase change material whereby the phase change material changes from a first state, in which the structure is disposed in the first orientation, to a second state, in which the structure is disposed in a second orientation. The MEMS elements may be fabricated using conventional surface micromachining techniques. In the illustrative embodiment, each MEMS element is attached to a substrate by at least one hinge which allows rotation of the MEMS element out of the plane of the substrate to a selected angle. To enable mass assembly of the MEMS elements, the MEMS elements are rotated to the selected angle using either surface tension forces of a liquid phase change material or shrinkage of a solid phase change material. In the illustrative embodiment, the phase change material is solder and the step of inducing a phase change in the phase change material includes the step up applying heat.

Abstract: In a pulse tube refrigerator the refrigeration efficiency has been improved by reducing the on-off valve loss. A second space 47 in a cylinder member 41 is connected with a second high pressure on-off valve 23 and a second low pressure on-off valve 24. A buffer side on-off valve 25 is provided between the buffer space (a buffer tank 50) and the second space 47. By opening the buffer side on-off valve 25 before the second high pressure on-off valve 23 or the second low pressure on-off valve 24 is open, the pressure in the second space 47 can be the intermediate pressure. Since the pressure difference when the valves are open is decreased, the on-off valve loss can be decreased.

The system includes a controller able to execute a program to alter certain aspects of the system to provide for a maximum power transfer and substantially stall free start up of the thermal dynamic cycle engine. Generally the controller is able to alter the current load to achieve a selected stroke length, pattern or temperature of a heater head of the engine. The system allows for generally stall free start-up and continuous control for maximum power (with maximum power factor) transfer from the thermal cycle engine or the associated alternator.
